The evaluation board was fine before, but I removed the charge and discharge resistors when adjusting the touch buttons. There is a 3.3M pin that has not been soldered back. The board has been powered...
I have heard many people ask me this question: "I don't have a foundation, can I learn electronics?" I tell you "yes", do you believe it? A sentence I said a few years ago makes a lot of sense: in any...
For example, (1920*6)*(1080*5)@10fps, H.264, or H.265 is better. Can DM8168 only realize 3-way H.264 1920*1080 real-time compression? Although the maximum frame rate reaches 60fps, it is impossible to...
At present, the development of wireless power supply technology for electric vehicles (EVs) is becoming more and more active. In 2012, Volvo of Sweden established Volvo Technology Japan in Tokyo as...[Details]
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
Automotive applications are particularly sensitive to EMI events, which are unavoidable in a noisy electrical environment consisting of a central battery, bundled wiring harnesses, various inductiv...[Details]
In this article, the high-performance DSP developed by TI can be used as an effective confidentiality method if it is applied to PC encryption cards.

Although it is relatively easy to check the stability of a simple amplifier at lower frequencies, it may be much more difficult to evaluate the stability of a more complex circuit. This artic...[Details]
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
In the previous series, we have listed some basic knowledge of C language in Tables 1 to 3. We hope that beginners can strengthen their memory of the above tables and gradually learn to use them wh...[Details]
Contact resistance
is the resistance to current flow through a closed pair of contacts. This type of measurement is performed on devices such as connectors,
relays
, and switches. The...[Details]
